Question

The bob of a simple pendulum is made of wood. What will be the effect on the time period if the wooden bob is replaced by an identical bob of aluminium?

Answer 1

As you know, time period of simple pendulum , T = $2\pi\sqrt{\frac{l}{g}}$

Where l is length of bob of simple pendulum.
g is acceleration due to gravity.

here it is clear that time period of siimple pendulum doesn't depend on mass of bob or material property of bob. it just depends on length of bob and acceleration due to gravity .

so, if we replace the wooden bob by identical bob of aluminium, time period remains constant.

Answer 2

Answer:

The time period will remain the same as it is independent of the mass & material of the Bob.
